Background technology
Along with the fast development of computer technology, cloud computing is more and more concerned, no matter is the Internet manufacturer and operator, or communicates manufacturer and basic network operator, all shows great concern to cloud computing.
The cloud computing of narrow sense refers to payment and the using forestland of Internet technology (IT, InternetTechnology) infrastructure, refers to obtain required resource by network in the mode as required, easily expanded; The cloud computing of broad sense refers to payment and the using forestland of service, refers to obtain required service by network in the mode as required, easily expanded.It is relevant with software, the Internet that this service can be IT, and also can be other service arbitrarily, cloud computing has the advantages such as ultra-large, virtual, safe and reliable.For Virtual network operator, cloud computing can make operation cost and Operation and Maintenance cost greatly reduce, and reaches the object of energy-saving and emission-reduction, in addition, can also expand the scope of operation, and not only be limited to pipeline operation.Under cloud computing environment, all resources all can be runed, and can provide as service, comprise application program, software, platform, disposal ability, storage, network, computational resource and other infrastructure etc.For user, cloud computing makes at any time, consumption service everywhere becomes possibility, and user can not need great amount of investment and obtain the IT resource needed for operation business, can rent according to the demand of oneself completely, IT resource is the same with coal gas as water, electricity, obtains as required and charging.
Cloud computing generally has three kinds of main service modes, namely infrastructure serve (IaaS, InfrastructureasaService,), namely platform serve (PaaS, PlatformasaService) and software namely serve (SaaS, SoftwareasaService).
Under cloud computing scene, a large amount of user profile all concentrates on cloud computing provider, compared with traditional Internet service, its information is more concentrated, information assets is worth attack that is higher, that face also can be more, and this only has legal user can access authorized resource with regard to requiring cloud computing service provider can have more powerful User identification mechanism to ensure.
Identity federation is a kind of method that can simplify user and log in, and refers to and links from the account of different service provider and the account of identity provider (or authentication center).After federated identity, by identifier unique for establishment one or alliance's token, by the user identity link of setting up in different service provider.Can make in this way after user logs in identity provider access authentication token, this authentication token is just free to for accessing all service providers having alliance with this identity provider.Identity federation is different from traditional centralized user management; the account information of service provider does not need to concentrate and is kept in the server of certain authentication center; and only need to preserve some mapping relations in authentication center; this can reduce the single point failure problem damaged because of identity provider or close down and cause; and the safety of energy more effective protection account, the loss risk of account information also can effectively be disperseed.
Identity federation has been the very effective solution of one of single-sign-on, has practical application widely.The identity federation scheme that current network is applied is all generally based on some main standard criterions, such as: the identity federation framework (ID-FF of Liberty Alliance (LibertyAlliance), IdentityFederationFramework), structured message standard promotes tissue (OASIS, OrganizationfortheAdvancementofStructuredInformationStan dards) security assertion markup language (SAML, and WS-Federation specification SecurityAssertionMarkupLanguage), these specifications are identity federation specifications of current main flow, application widely.Generally, all service providers in an identity federation and identity provider all realize based on same standard criterion, identical specification is used because only have, just may ensure that identity federation token can be identified by all allied members, the free transmission of alliance's token in whole alliance can be realized thus.If the identity federation specification that some service provider or identity provider are supported is inconsistent, so alliance just cannot set up, traditional solution is that as much as possible the going of service provider or identity provider realizes identity federation standard criterion, to guarantee to realize alliance with other each side.But this way cost is very high, the expense of service provider or identity provider is caused greatly to increase.
